Appication notes

  1. Is it an industry requirement that application notes always contain an
    error?

    I've just been using C code from a 1-wire application note and it
    didn't work. It took a couple of hours with the scope checking
    timings etc before I spotted a wrong hex address in the code.

    Grrr.

    They were testing you to see if you were paying a attention!

    Sometimes that works to let them know how interested their
    users/readers really are about what they are looking at.

    Well, that's my story and I am sticking to it. :)

    Support material is a loss item. As you realize, marketing gets a bigger
    share of the budget and customer support is low on their list.

    ** Yawnnnnnnnn.....

    Let me explain how documents get created. People who know what they are
    doing create circuits, programs, etc. that work. [Hey, excluding dry
    labbers.] Marketing doesn't like how your schematic looks, blah blah
    blah. They pretty things up and introduce errors. Many schematics in
    datasheets do not like like they came from schematic capture
    because....well... they didn't come from schematic capture. Some
    marketing type took a good schematic captured circuit and then drew it
    in Visio or whatever.

    Here is a clue on how to sort fact from fiction in datasheets. Scope
    photo: fact. Spreadsheet data: often fiction or at least prone to error
    because some marketing type screwed with it. LTC as an example has many
    scope photos or at least documents that look like they came right off an
    instrument (spectrum analyser, DSA, AP, etc.). I suspect design
    engineering at LTC has a bit more control over the marketing types.

    Without even seeing your code error, I have this nagging suspicion is
    some marketing type didn't like the font in the code they were given and
    re-typed it, leaving out a line or adding a bug. In C, a + and ++ are
    very different!

    I don't know if they still do so but UK Ordnance Survey maps used to have
    one deliberate (minor) error per map for copyright reasons. Only one person
    with access to the safe containing the nature of each error

    He posts here from time to time, and he's pretty good; much better
    than Raveninghorde.
    I don't recall having seen your nym at all - maybe you should have
    lurked for a bit longer before you decided who you should call an
    asshole.

    It's AlwaysWrong.
    I'd rather he just lurk forever.

    Now, them's fighting words! As an application engineer for ten years,
    I can tell you that we WERE engineers, in every aspect!
